Why do there appear to be so many individual substances in the adopted FEI Prohibited Substances List?
A. Over time a large number of substances which could influence the performance of the competition horse have emerged from the pharmaceutical industry. All the substances listed have been viewed as prohibited by the FEI for some time and modern instruments in laboratories can very easily test for thousands of substances at once. Similar lists of substances are also prohibited by other organizations monitoring equine sport, such as racing authorities.
